(Configuration of front side of pachinko machine)
1 is a front view of the pachinko machine 10, FIG. 2 is a perspective view of the pachinko machine 10, and FIG. 3 is a perspective view of a front frame of the pachinko machine 10. As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. I have. Below, the structure of the outer frame 11 and the inner frame 12 is demonstrated separately.

  The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of a light metal such as resin or aluminum. This is because such a configuration can reduce the weight of the pachinko machine.

  On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the position where the handle (game ball launching handle 18 described later) is installed as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as the axis. If the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation location side (the right side of the pachinko machine 10 in FIG. 1), the game ball launching handle is opened when the inner frame 12 is opened. This is because the 18 heads and the like interfere with adjacent pachinko machines and card units (ball lending units), and the inner frame 12 cannot be fully opened. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  Further, the inner frame 12 has a lower pan unit 13 at the lowermost part thereof, and a front frame set 14 attached to the left and right sides of the inner frame 12 so as to be openable and closable about a vertical opening / closing axis, and a resin base 25. (Refer to the figure) and a game board 30 described later attached to the rear side of the resin base 25 are provided. Each of these configurations will be described in detail below.

  The lower plate unit 13 is fixed to the front frame base member as a part of the front frame set 14. On the front side of the lower plate unit 13, a lower plate 15, a ball removal lever 17, a game ball launching handle 18, and an effect button 79 are provided. The lower tray 15 serving as a ball receiving tray is provided at substantially the center of the lower tray unit 13 and plays a role of stopping a game ball discharged from the discharge port 16 when the upper tray described later becomes full. is there. The ball removal lever 17 is for removing a game ball in the lower tray 15, and by moving the ball removal lever 17 to the left in FIG. 1, a predetermined location on the bottom surface of the lower tray 15 is opened. The game ball stopped in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launching handle 18 by the player, the game ball is driven toward a game board 30 described later by a game ball launching device having a launch solenoid. A sound output port 24 for outputting sound from a speaker is provided at the upper part of the front frame set 14.

  On the other hand, an upper plate 19 as a receiving tray for game balls is provided integrally with the front frame set 14 at a lower portion of the front frame set 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. In addition, an effect button 79 for the player to perform an operation such as changing the background of the decorative symbol display device 42 is provided at the lower left of the upper plate 19.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or the like. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and lighting or blinking in the big hit gaming state, it is in a big hit gaming state It is the structure which alert | reports.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button, a return button, and a frequency display unit. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. The The return button is operated when requesting the return of a card or the like inserted into the card unit. The frequency display section displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

(Feature configuration)
Next, the configuration of the game board 30 will be described. 4 is a front view of the game board 30, FIG. 5 is a rear view of the game board 30, FIG. 6 is a left side view of the game board 30, FIG. 7 is a right side view of the game board 30, and FIG. 9 is a bottom view of the game board 30, FIG. 10 is a perspective view of the front side of the game board 30, FIG. 11 is a perspective view of the back side of the game board 30, and FIG. 12 is an exploded perspective view of the front side of the game board 30. 13 and 13 are exploded perspective views of the back side of the game board 30. FIG.

  The gaming board 30 has a front shape in which the upper left corner of the roughly oblong rectangle is roughly arc-shaped and the upper right and lower left corners are notched inward and has a sufficient shape retaining property. It is the plate-shaped member which has. On the front surface (front surface) of the game board 30, a game area launched from the launching device, that is, a game area to which the launch ball is guided is provided. This game area is formed in a slightly vertically long elliptical shape so as to occupy most of the area including the central portion of the front surface (front surface) of the game board 30.

  As shown in FIGS. 12 and 13, the game board 30 includes a game board member 301 and a backing member 302. The game board member 301 is a plate-like member formed by molding a transparent acrylic resin. The game board member 301 constitutes a large part of the game board 30, and has an outer shape substantially corresponding to the outer shape of the game board 30 as well as the game board 30 as a whole. It has a small area and a slightly thin wall thickness (about half in this embodiment). The central portion of the lower edge of the game board member 301 extends slightly downward to form a substantially laterally rectangular parallelepiped (square bar-like) lower extension portion 301E, and the central portion of the left edge of the game board member 301 is A left side extending portion 301F having a substantially trapezoidal shape is formed extending slightly to the left. In addition, positioning holes corresponding to positioning bosses 306T, 306B, 306L, and 306R of a backing member 302 (to be described later) are formed at a plurality of peripheral edge portions located outside the game area in the game board member 301. . Further, as shown in FIG. 13, in the vicinity of the upper end of the right edge portion of the game board member 301, it is substantially U-shaped when viewed from the back and has four corners (two outer corner portions and two inner corner portions). ) Is recessed in a rounded corner shape, and a main display unit mounting notch 301C is formed for mounting the main display unit 371 in a state where a connector protruding from the back of the main display unit 371 described later is received inside. ing.

  The backing member 302 is divided into four parts of an upper piece 302T, a lower piece 302B, a left piece 302L, and a right piece 302R corresponding to the upper edge, the lower edge, the left edge, and the right edge of the game board member 301, respectively. The four divided pieces 302T, 302B, 302L, and 302R are individually assembled to the game board member 301 and connected and fixed to each other so as to form a frame shape as a whole. Each of the four divided pieces 302T, 302B, 302L, and 302R is a molded body made of an opaque resin that is softer than the game board member 301 and is colored (black).

  The backing member 302 is a frame-shaped member constituting the outer peripheral portion of the game board 30 and is slightly large, but as described above, it is divided into four divided pieces 302T, 302B, 302L, 302R. By configuring them and forming them as a frame as a whole, they can be molded without using a large mold.

  As shown in FIG. 14, the upper piece 302T is partially cut while virtually cutting the game board 30 along a horizontal plane at a height position slightly below the upper end, leaving a back wall from the front to the inside. A recess having a front shape and a depth that matches the upper edge of the game board member 301 is formed so that the inner edge (lower edge) of the inner wall of the recess is the upper edge of the game area. It is formed in an arc shape that matches the outer shape of the part, and is substantially equal to a virtual solid that has a generally arcuate outer shape as a whole. With this configuration, the upper piece 302T is formed with a back wall portion 303T corresponding to the upper end edge portion of the back surface of the game board member 301, and the upper edge portion of the game board member 301 is formed from the outer edge of the back wall portion 303T. A front peripheral wall 304T corresponding to the end surface extends forward. A first positioning boss 305T for positioning with respect to the inner frame 12 protrudes from the upper right portion of the front surface of the upper piece 302T, and a game board member is provided near the upper end (center) and the right end of the rear wall portion 303T. Second positioning bosses 306T for positioning with respect to 301 are respectively provided.

  On the back side of the back wall portion 303T in the upper piece 302T, as shown in FIG. 15, lattice-like ribs 307T that run vertically and horizontally at intervals of about 10 mm to about 20 mm on average are formed although not strictly constant. Yes. In other words, the rear side of the back wall portion 303T of the upper piece 302T is basically open at the rear side, and the outer periphery is the peripheral wall (the opposite side from the outer edge of the base end portion of the front peripheral wall portion 304T, that is, the rear side). A rear peripheral wall extending to the rear and an inner peripheral wall 308T, which will be described later, and the inner space is partitioned so as to be subdivided by a lattice-like rib 307T. The rear end edge of the grid-like rib 307T coincides with the position of the rear side surface of the upper piece 302T. The inner edge (lower edge) of the inner wall portion 303T has an arc shape as described above, and an inner peripheral wall 308T that curves in a front view arc shape extends backward from the arc-shaped inner edge. A first circumferential rib 310T having a slightly larger diameter than the inner peripheral wall 308T is formed in a space behind the inner wall 308T in a space behind the inner wall 308T in the upper piece 302T. Further, the grid-like rib 307T between the inner peripheral wall 308T and the first peripheral rib 310T is in a state in which the rear end portion is cut out by a predetermined depth, that is, the rear end edge is located from the position of the rear side surface of the upper piece 302T. It is in a state where it is slightly retreated to the inner back side (front side). Accordingly, the inner peripheral wall 308T, the first peripheral rib 310T, and the rear end edge of the grid-like rib 307T between them are recessed by a predetermined depth from the rear side of the upper piece 302T and extend in a front view arc shape. An outer groove 316T is formed. On the other hand, the inner peripheral wall 308T is bent downward at a position slightly inward (center side) from the left end (right end in FIG. 15) and extends slightly vertically, and then folded again to the left side (right side in FIG. 15). It extends to the lower end of the upper piece 302T along an arcuate track that is the same (concentric) as it folds downward, so that the left end of the upper piece 302T is vertically (in the radial direction) higher than other parts. ) Wide. Further, in the band at a predetermined interval inside the left end portion of the inner peripheral wall 308T, the rear end portion of the lattice-like rib 307T is cut out by a predetermined depth, whereby the inner peripheral wall 308T and the inner lattice wall 308T inside the inner peripheral wall 308T. An inner groove 315T that is recessed by a predetermined depth from the rear side surface of the upper piece 302T by the rear end edge (notch) of the rib 307T and extends in a slightly smaller-diameter front view arc shape (concentric) like the outer groove 316T. It is configured. The inner groove 315T has a smaller amount (depth) of the rear end portion of the grid-like rib 307T than the outer groove 316T, and is therefore shallower than the outer groove 316T.

  As shown in FIG. 15, in the back side of the horizontal lower end edge of the right end portion and the left end portion of the upper piece 302T, it is recessed in a substantially inverted U shape (substantially semicircular shape) inward (upward). Screw insertion portions 319T and 320T each surrounded by a peripheral wall extending in a front shape and having a screw insertion hole formed in the center are formed.

  As shown in FIG. 16, the lower piece 302B virtually cuts the lower end portion of the game board 30 and partially cuts out from the front surface while leaving a back wall in the inner part. A recess having a front shape and a depth that matches the lower edge of 301 is formed, and the inner edge (upper edge) of the inner wall of the inner wall of the recess is an arc shape that matches the outer shape of the lower edge of the game area. The upper side of the substantially horizontally long rectangle is shaped so as to be substantially equal to a virtual solid body having an outer shape curved inwardly (lower side). With this configuration, the lower piece 302B is formed with a back wall portion 303B corresponding to the lower end edge portion of the back surface of the game board member 301, and the lower edge portion of the game board member 301 from the outer edge of the back wall portion 303B. A front peripheral wall portion 304B corresponding to the end surface of the front surface extends forward. Third positioning bosses 306B for positioning with respect to the game board member 301 project from the vicinity of the lower left end and the upper right end of the rear wall portion 303B. Further, the central portion of the lower end of the front peripheral wall portion 304B is cut open at an interval equal to the width of the lower extension portion 301E of the game board member 301.

  As shown in FIG. 17, lattice ribs 307B are formed on the back side of the back wall portion 303B of the lower piece 302B in the same manner as the lattice ribs 307T of the upper piece 302T. Therefore, as in the case of the upper piece 302T, the rear part of the lower piece 302B behind the rear wall 303B is basically open at the rear side, and the outer periphery is a peripheral wall (the base end of the front peripheral wall 304B). The outer peripheral edge is surrounded by a rear peripheral wall extending to the opposite side, that is, the rear side, and an inner peripheral wall 308B, which will be described later, and the internal space is partitioned so as to be subdivided by the lattice ribs 307B. As described above, the inner edge (upper edge) of the back wall portion 303B has an arc shape, and an inner peripheral wall 308B that curves in a front view arc shape extends rearward from the arc-shaped inner edge. A second circumferential rib 310B having a slightly larger diameter than the inner peripheral wall 308B is formed in a space behind the inner wall 308B in the space behind the inner wall 308B in the lower piece 302T. Further, the grid-like ribs 307B between the inner peripheral wall 308B and the second peripheral ribs 310B have a state in which the rear end portion is cut out by a predetermined depth, that is, the rear end edge is the position of the rear side surface of the lower piece 302B. It is in a state of retreating slightly to the inner back side (front side). As a result, the inner peripheral wall 308B, the second peripheral rib 310B, and the rear end edge of the grid-like rib 307B between them are recessed by a predetermined depth from the rear side of the lower piece 302B to form a front view arc shape. An extending inner groove 315B is formed. Further, the left end portion (the right end portion in FIG. 17) of the lower piece 302B is spaced apart from the inner groove 315B by a predetermined distance and has two third circumferential shapes having a larger diameter than the second circumferential rib 310B. Ribs 309B are formed, and the grid-like ribs 307B between the two third circumferential ribs 309B are cut out by a predetermined depth, and the two third circumferential ribs 309B and the grid-like ribs between them The rear end edge of 307B constitutes an outer groove 316B that is recessed by a predetermined depth from the rear side surface of the lower piece 302B and extends in a front view arc shape. The depth of the outer groove 316B is equal to the depth of the outer groove 316T in the upper piece 302T, while the depth of the inner groove 315B is equal to the depth of the inner groove 315T in the upper piece 302T.

  As shown in FIGS. 16 and 17, the central portion of the lower piece 302B is recessed from the upper edge slightly downward, extends upward from the bottom, and has a generally saddle shape when viewed from the side in the front and upward direction. A guide piece 317B is formed in a bent shape, and thereby has an inclined surface at the upper end that is slightly inclined backward. The guide piece 317B is for guiding a game ball toward the ball discharge path from an out port 36 described later. In addition, as shown in FIG. 17, a recessed surface portion 318B that is recessed into a substantially rectangular shape that is horizontally long when viewed from the front is formed at a position slightly above the lower end of the center on the back surface side of the lower piece 302B. . On the other hand, the spherical assembly plate arranged on the back side of the lower piece 302B has a projection (not shown) that fits into the recessed surface portion 318B, and the projected portion fits into the recessed surface portion 318B. Thus, the lower piece 302B and the ball assembly plate are arranged in contact with each other so as to form a vertical stepped shape, that is, in a fitting posture. In this central portion of the gaming machine, if there is a gap between the lower piece 302B and the ball assembly plate, for example, there is a possibility that an unauthorized operation is performed by entering some unauthorized tool into the interior through this gap from below. However, as described above, the lower piece 302B and the ball assembly plate are configured to be fitted in a stepped vertical cross section, making it difficult for such an unauthorized tool to enter. At this time, if the recessed surface portion 318B is recessed too deeply, a gap is likely to be formed inside, and the projecting portion to be fitted has a large protruding length, so that the strength tends to decrease structurally. Inside the recessed surface portion 318B, the inner back surface reappears slightly toward the surface side (rear side), so that the recessed surface portion 318B is shaped to be shallowly recessed. At this time, as shown in FIGS. 16 and 17, in this central portion, the back side (rear side) is a wall surface and the front side (front side) is forward from the wall surface, contrary to the other parts (both sides). A grid-like rib is formed in the space as an open space. From the viewpoint of appearance, it is desirable that the front side surface (front side surface) is a wall surface and the back side (rear side) is opened to form a grid-like rib in the open space. Therefore, the backing member including the lower piece 302B is included. In the entire 302, the front side surface (front side surface) is basically the wall surface. However, as described above, the rear side surface (rear side surface) becomes the wall surface by reversing only the central portion of the lower piece 302B. The lower piece 302B and the ball assembly plate can be brought into contact with each other with no gap between them, making it difficult for an unauthorized tool to enter, and the inclined portion of the guide piece 317B can be formed. It is also possible to mold to have a uniform thickness (because if the back side (rear side) is the open side, the mold release direction will also be rearward during molding, so it will be lowered rearward. The inclined part of the inclined guide piece 317B has a uniform thickness. This is because it becomes difficult to mold the).

  As shown in FIG. 16, the upper edge of the lower piece 302B forms an arc shape from the center and gradually increases in height to both sides. It has a shape that extends downward and then extends horizontally to reach the right end. On the other hand, on the way to the left, it tilts downward near the left end and extends to the lower left, and then extends to the lower right while inclining so as to return to the inside (right side). In other words, the upper left corner of the lower piece 302B extends slightly to the upper left along the arc shape of the upper edge. As shown in FIG. 17, the back side of the lower inclined portion on the right side is surrounded by a peripheral wall extending in a front shape recessed in a U shape toward the inside (lower right in FIG. 17). A screw insertion portion 319B having a screw insertion hole is formed, and a screw insertion portion 319B having the same configuration is also provided in the vicinity of the right end (left end in FIG. 17) of the horizontal portion except that it is recessed vertically downward. Is formed. On the other hand, the screw insertion portion having the same configuration as the screw insertion portion 319B of the lower inclined portion on the right side except that it is formed slightly wider on the back side of the lower end portion of the lower inclined portion extending to the lower left on the left side. 320B is formed.

  As shown in FIG. 18, the left piece 302L virtually cuts the left side of the game board 30 and partially cuts out from the front while leaving a back wall in the inner part. A recess having a front shape and a depth matching the left side of the game is formed, and the inner edge (right side edge) of the back wall of the recess is formed in an arc shape that matches the outer shape of the left side of the game area, and is elongated vertically as a whole. It is formed so as to be substantially equal to a virtual solid having an extending outer shape. With this configuration, the left piece 302L is formed with a back wall portion 303L corresponding to the left side portion of the back surface of the game board member 301, and from the outer edge of the back wall portion 303L to the end face of the left side portion of the game board member 301. A corresponding front peripheral wall portion 304L extends forward. A fourth positioning boss 305L for positioning with respect to the inner frame 12 protrudes from the lower left portion of the front surface of the left piece 302L, and the game board member 301 is provided near the upper left end and the lower left end of the rear wall portion 303L. The fifth positioning bosses 306L are positioned so as to project with respect to each other. Further, the central portion of the front peripheral wall portion 304L is cut open at an interval equal to the width of the left extension portion 301F of the game board member 301.

  As shown in FIGS. 19, 20, and 24, lattice ribs 307L are formed on the back side of the rear wall portion 303L of the left piece 302L in the same manner as the lattice ribs 307T of the upper piece 302T. Therefore, as in the case of the upper piece 302T, the rear side of the rear wall portion 303L of the left piece 302L is basically open at the rear side surface and the outer periphery is a peripheral wall (the base end portion of the front peripheral wall portion 304L). It is surrounded by a rear peripheral wall extending from the outer edge to the opposite side, that is, the rear side, and an inner peripheral wall 308L, which will be described later, and the inner space is partitioned so as to be subdivided by the lattice ribs 307L. As described above, the inner edge (right edge) of the inner wall 303L has an arc shape, and an inner peripheral wall 308L that curves in a front view arc shape extends rearward from the arc-shaped inner edge. A fourth circumferential rib 310L having a slightly larger diameter than the inner peripheral wall 308L is formed in a space behind the inner wall 308L in a space behind the inner wall 308L in the left piece 302L. Furthermore, as is clear from FIG. 24 in particular, the lattice-like ribs 307L between the inner peripheral wall 308L and the fourth peripheral ribs 310L are in a state in which the rear end portions are notched by a predetermined depth, that is, the rear end edges are It is in a state in which it retreats slightly inward (front side) from the position of the rear side surface of the left piece 302L. Accordingly, the inner peripheral wall 308L, the fourth peripheral rib 310L, and the rear end edge of the grid-like rib 307L between them are recessed by a predetermined depth from the rear side surface of the left piece 302L and extend in a front view arc shape. An inner groove 315L is formed. Further, a fifth circumferential rib 309L having a larger diameter than the fourth circumferential rib 310L is formed at a predetermined interval from the inner groove 315L. Furthermore, the fifth circumferential rib 309L extends from the upper end to the lower end of the left piece 302L, similar to the inner circumferential wall 308L and the fourth circumferential rib 310L. A sixth circumferential rib 322L having a larger diameter than the fifth circumferential rib 309L is locally formed on the lower side portion of 302L with a predetermined interval between the fifth circumferential rib 309L. In particular, as is apparent from FIG. 24, the lattice rib 307L between the fifth circumferential rib 309L and the sixth circumferential rib 322L is notched by a predetermined depth, and as shown in FIG. The notch of the rib 307L extends along the fifth circumferential rib 309L to the upper end of the left piece 302L while maintaining a constant width. In other words, the sixth circumferential rib 322L is locally formed on the lower side of the left piece 302L, but the notches of the fifth circumferential rib 309L and the lattice rib 307L are formed from the upper end of the left piece 302L. It is formed over almost the entire length up to the lower end. By the fifth circumferential rib 309L, the sixth circumferential rib 322L, and the cutout portion of the grid-like rib 307L, the upper end of the left piece 302L is recessed in a predetermined depth from the rear side surface of the left piece 302L. An outer groove 316L extending from the portion to the lower end is configured. The depth of the outer groove 316L is equal to the depth of the outer groove 316T in the upper piece 302T, while the depth of the inner groove 315L is equal to the depth of the inner groove 315T in the upper piece 302T.

  The upper end edge of the left piece 302L is horizontally formed corresponding to the lower end edge of the left end of the upper piece 302T, while the lower end edge of the left piece 302L is the lower left of the lower piece 302B. Corresponding to the downwardly inclined portion extending to the right side, the right end is formed into a shape extending upwardly to the right. At the center of the end face of the upper end edge of the left piece 302L, a generally inverted U-shaped (substantially semicircular) piece as viewed from the front protrudes upward from the front edge close to the front surface of the back wall 303L. A screw insertion portion 320L is formed in which a peripheral wall extends rearward from the peripheral edge of the upper portion 302T, and a long hole-like screw insertion hole extending slightly in the extending direction is formed in the center. The screw insertion portion 320T at the left end of the upper piece 302T On the other hand, the lower end portion of the upper inclined portion of the lower end portion of the left-side piece 302L is threaded at the upper end portion except for being slightly wider. A screw insertion portion 320L having the same configuration as that of the portion 320L is formed, and can be fitted from the inside to the screw insertion portion 320B at the left end of the lower piece 302B. A small piece perpendicular to the front-rear direction extends rightward from the right side surface of the peripheral wall of the screw insertion portion 320L at the upper end of the left piece 302L, and an alignment protrusion 321L projects forward from the center of the small piece. On the other hand, an alignment hole 321T is formed on the right side of the screw insertion portion 320T at the left end of the upper piece 302T (see FIG. 15), and the alignment protrusion 321L can be fitted into the alignment hole 321T. It is like that.

  As shown in FIG. 21, the right side piece 302R virtually cuts the right side portion of the game board 30 and partially cuts out from the front surface while leaving a back wall inwardly, so that the game board member 301 A concave portion having a front shape and a depth that matches the right side of the concave portion is formed, and the inner edge (left side edge) of the inner wall of the concave portion has a substantially arc shape that matches the outer shape of the right side of the game area, and as a whole vertically It is shaped so as to be substantially equal to a virtual solid having a long extending outer shape. With this configuration, the right piece 302R is formed with a back wall portion 303R corresponding to the right side portion of the back surface of the game board member 301, and from the outer edge of the back wall portion 303R to the end face of the right side portion of the game board member 301. A corresponding front peripheral wall portion 304R extends forward. Sixth positioning bosses 306R for positioning with respect to the game board member 301 are projected from the vicinity of the upper end and the center of the lower end of the back wall portion 303R in the right piece 302R. Further, a position in the vicinity of the upper end of the rear wall portion 303R above the sixth positioning boss 306R has a rectangular front shape with rounded corners, and matches and communicates with the main display unit mounting notch 301C. A wiring insertion hole 323R for inserting a wiring of a main display unit 371 described later is formed.

  As shown in FIG. 22, lattice ribs 307R are formed on the back side of the back wall portion 303R of the right piece 302R in the same manner as the lattice ribs 307T of the upper piece 302T. Therefore, as in the case of the upper piece 302T, the rear side of the rear piece 303R in the right piece 302R is basically open at the rear side, and the outer periphery is the peripheral wall (the base end of the front peripheral wall part 304R). It is surrounded by a rear peripheral wall extending from the outer edge to the opposite side, that is, the rear side, and an inner peripheral wall 308R, which will be described later, and the internal space is partitioned so as to be subdivided by the lattice ribs 307R. As described above, the inner edge (left edge) of the rear wall portion 303R has a substantially arc shape, and an inner peripheral wall 308R that curves in a substantially arc shape when viewed from the front extends from the substantially arc-shaped inner edge. A seventh circumferential rib 310R having a slightly larger diameter than the inner circumferential wall 308R is formed in a space behind the inner wall 308R at a space behind the inner wall 308R at the lower end of the right piece 302R. Yes. Further, the grid-like ribs 307R between the inner peripheral wall 308R and the seventh peripheral ribs 310R are in a state in which the rear end portion is cut out by a predetermined depth, that is, the rear end edge is located from the position of the rear side surface of the right piece 302R. It is in a state where it is slightly retreated to the inner back side (front side). As a result, the inner peripheral wall 308R, the seventh peripheral rib 310R, and the rear end edge of the lattice rib 307R between them are recessed by a predetermined depth from the rear side of the right piece 302R and extend in a front view arc shape. An inner groove 315R is configured. The depth of the inner groove 315R is equal to the depth of the inner groove 315T in the upper piece 302T.

  The upper edge of the right piece 302R is horizontally formed corresponding to the lower edge of the right end of the upper piece 302T, while the lower edge of the right piece 302R is the lower end of the right end of the lower piece 302B. Corresponding to the edge, it extends horizontally from the right end to the left, tilts upward near the left end, and extends to the upper left. At the center of the end face of the upper end edge of the right piece 302R, a generally inverted U-shaped (substantially semicircular) piece as viewed from the front protrudes upward from the front edge near the front surface of the rear wall 303R. A screw insertion portion 319R is formed in which a peripheral wall extends rearward from the peripheral edge and a long hole-like screw insertion hole extending slightly in the extension direction at the center is formed, and the screw insertion portion 319T at the right end of the upper piece 302T is formed. On the other hand, a screw insertion portion having substantially the same configuration as the screw insertion portion 319R of the upper end portion is provided at the horizontal portion and the upward inclined portion at the lower end portion of the right piece 302R. 319R is formed and can be fitted from the inside to the screw insertion portion 319B at the right end of the lower piece 302B.

  As shown in FIG. 4 and FIG. 10, a rail unit 50 for guiding a game ball (launch ball) launched from the game ball launcher to the upper part of the game board 30 is attached to the game board 30. A game ball launched in accordance with the turning operation of the ball launch handle 18 is guided to a predetermined game area through the rail unit 50. As shown in FIGS. 12 and 13, the rail unit 50 is configured by a ring-shaped metal plate, and includes an inner rail 51 and an outer rail 52 having the same width and configured as an inner and outer double. The rear edge (the edge facing the game board 30) of the inner rail 51 and the outer rail 52 has clasps 56 (see FIG. 4 and FIG. 10) at intervals from one end to the other end. 12 and FIG. 13). The inner rail 51 is formed in a substantially partial annular shape except for about ¼ of the upper portion, and the outer rail 52 is formed such that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip of the inner rail 51 (upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes.

  The game area is partitioned and formed in a substantially circular shape by the inner peripheral part (inner and outer rails) of the rail unit 50. In particular, in this embodiment, the game castle partitioned on the board surface of the game board 30 is more than conventional. It is much larger.

Next, an outline of the assembly procedure of the game board 30 will be described.
(1) First, the backing member 302 is assembled to the game board member 301.
Specifically, first, the upper piece 302T and the lower piece 302B of the backing member 302 are inserted into the positioning holes of the gaming board member 301 while the second positioning boss 306T and the third positioning boss 306B are inserted into the positioning holes of the gaming board member 301. It positions and arrange | positions at an upper end edge part and a lower end edge part, respectively. Next, the left side piece 302L and the right side piece 302R, and the fifth positioning boss 306L and the sixth positioning boss 306R are inserted into the positioning holes of the game board member 301 from above the upper piece 302T and the lower piece 302B of the backing member 302. At the same time, the screw insertion part 320L of the left piece 302L and the screw insertion part 319R of the right piece 302R are fitted into the screw insertion parts 319T and 320T of the upper piece 302T and the screw insertion parts 319B and 320B of the lower piece 302B, respectively. The game board member 301 is positioned and arranged at the left edge portion and the right edge portion, and screws are screwed in from the screw insertion portion 320L of the left piece 302L and the screw insertion portion 319R of the right piece 302R. 302 upper piece 302T, lower piece 302B, left piece 302L and right piece 30 Securing the R on the game board member 301.

  In this way, the upper piece 302T, the lower piece 302B, the left piece 302L, and the right piece 302R of the backing member 302 are individually assembled to the back surface of the game board member 301 while being connected to each other, as shown in FIGS. As a whole, the central portion is formed in a frame shape that is opened in a slightly vertically long elliptical shape corresponding to the game area.

  Accordingly, the inner groove 315T of the upper piece 302T, the inner groove 315L of the left piece 302L, the inner groove 315B of the lower piece 302B, and the inner groove 315R of the right piece 302R of the backing member 302 are uniform in depth and width. As a whole, a substantially partial annular inner groove 315 corresponding to the entire inner rail 51 of the rail unit 50 is formed, and the outer groove 316T of the upper piece 302T and the outer side of the left piece 302L of the backing member 302 are formed. The side groove 316L and the outer groove 316B of the lower piece 302B communicate with each other with a uniform depth and width, and as a whole, a substantially partial annular outer groove 316 corresponding to the entire outer rail 52 of the rail unit 50 is configured. The At this time, as shown in FIG. 25, the depth D315 of the inner groove 315 is smaller than the depth D316 of the outer groove 316 (D315 <D316), that is, the inner groove 315 is shallower than the outer groove 316. Of the outer groove 316 is equal to the distance between the inner rail 51 and the outer rail 52, and the width W315 of the inner groove 315 is smaller than the width W316 of the outer groove 316 (W315 < W316).

  As described above, the upper piece 302T and the lower piece 302B of the backing member 302 are positioned and arranged on the game board member 301, and the left piece 302L and the right piece 302R are positioned and arranged from above the upper piece 302T. The upper piece 302T and the lower piece 302B of the backing member 302 are accurately positioned with respect to the game board member 301 by being screw-fixed to the game board member 301 together with the 302T and the lower piece 302B. be able to. That is, in this way, after the first set of the upper piece 302T and the lower piece 302B is arranged, the subsequent set of the left piece 302L and the right piece 302R is arranged thereon to arrange the game board member 301. In the case of a two-stage arrangement process that is fixed to the game board, the subsequent set is indirectly arranged with respect to the game board member 301 with the previous set interposed therebetween. Although it is not easy to accurately position with respect to the plate member 301, on the other hand, since the first set is directly arranged with respect to the game plate member 301, it is relatively easy to position accurately. Easy. Among the four divided pieces 302T, 302B, 302L, and 302R of the backing member 302, the lower piece 302B is particularly accurate in assembling position from the standpoint of positioning of the game board 30 and the prevention of fraud. Therefore, it is desirable that the lower piece 302B is directly arranged and fixed to the game board member 301 as described above. For example, when the position of the lower piece 302B is shifted downward to a certain degree or more from the predetermined position, the game board 30 is brought into contact with the inner frame 12 by the lower piece 302B, and the vertical position is determined. There is a possibility that the upper and lower positions of the sphere will not be constant and affect the trajectory of the launch ball. On the other hand, if the position of the lower piece 302B is shifted upward from a predetermined position, the gap below the lower piece 302B may be widened to make it easier for an unauthorized tool to enter.

  At this time, the screw insertion portion 320L of the left piece 302L and the screw insertion portion 319R of the right piece 302R are both configured with a long hole-like screw insertion hole extending slightly in the extending direction as described above. Therefore, even if there is some positional deviation in the upper piece 302T or the lower piece 302B, the left piece 302L and the right piece 302R can be arranged and fixed while absorbing this positional deviation.

(2) Next, the rail unit 50 is attached to the game board member 301.
The inner rail 51 and the outer rail 52 constituting the rail unit 50 are attached to the game board member 301 at a plurality of locations by the clasp 56 as described above. The clasp 56 is a metal fitting bent into a long U-shape (hairpin shape), and is inserted through a small hole formed in the rear edge of the inner rail 51 and the outer rail 52. The inner rail 51 and the outer rail 52 are fixed to the game board member 301 by striking the front end portion against the game board member 301 while supporting the 51 and the outer rail 52 by being hooked inside the bent part. ing. When the clasp 56 is struck, the leading end of the clasp 56 penetrates the game board member 301 and slightly protrudes from the back surface, but the upper piece 302T, the lower piece 302B, the left piece 302L and the right piece 302R of the backing member 302 Insertion holes for receiving the tips of the gold 56 are respectively formed at corresponding positions. In this way, the tip of the clasp 56 penetrates the game board member 301 and slightly protrudes from the back surface, so that, for example, a thin plate-like illegal tool is inserted from the outside between the game board member 301 and the backing member 302 in this part. When trying to enter, there is also an advantage that it is obstructed by the tip of the clasp 56 and it is difficult to make further entry.

  In the manufacturing process of the pachinko machine 10, the rail unit 50 is laid as described above, and then the game board 30 in any stage before the nail and various winning devices are attached and completed, Although there are cases where a plurality of game boards 30 are stacked, according to the configuration of the game board 30 of the pachinko machine 10, a plurality of game boards 30 can be stably stacked. In this case, a plurality of game boards 30 are stacked so that another game board 30 is supported on the rail unit 50, but at this time, the game board is merely placed on the rail. If there is, the rail and the game board may be displaced along the board surface direction. In particular, in the case of a game board made of resin like the game board 30 of the pachinko machine 10, the rail and the game board slip. Because of this, it is difficult to stably stack a plurality of game boards. On the other hand, according to the configuration of the game board 30 of the pachinko machine 10, the inner surface 315 corresponding to the inner rail 51 of the rail unit 50 and the outer rail 52 are formed on the back side surface of the backing member 302. Since the corresponding substantially annular outer groove 316 is disposed, the inner rail 51 and the outer rail 52 of the rail unit 50 of another game board 30 are respectively fitted into the inner groove 315 and the outer groove 316 from below. A plurality of game boards 30 can be stacked as described above, and by fitting the inner grooves 315 and outer grooves 316 with the inner rails 51 and the outer rails 52, the (upper) game board 30 is separated from the (upper) game board 30. By restricting relative movement in the board surface direction with the game board 30 on the side, it is possible to prevent these game boards 30 from being displaced along the board surface direction, and thus a plurality of games. So that the 30 can be stacked stably. As described above, the structure in which the groove and the rail are fitted and the relative movement is restricted to suppress the deviation in the board surface direction is a game board made of a material such as a resin that is slippery with respect to the rail. This is particularly useful in other cases, or in other words, by making the groove and the rail fit together as described above, while ensuring the stability when stacking a plurality of game boards, the material of the game board Any material can be used without considering the degree of slipperiness with respect to the rail.

  Further, at this time, according to the configuration of the game board 30 of the pachinko machine 10, as described above, the inner groove 315 is shallower than the outer groove 316 (D315 <D316), so that it is schematically shown in FIG. When another game board (hereinafter also referred to as “upper game board”) 30H is stacked on a certain game board (hereinafter also referred to as “lower game board”) 30L, the outside of the upper game board 30H. The inner back surface (bottom surface) of the inner groove 315 of the upper game board 30H and the inner side of the lower game board 30L in a state where the inner back surface (bottom surface) of the side groove 316 and the outer rail 52 of the lower game board 30L do not contact each other. Since the rail 51 preferentially abuts, the upper game board 30H is supported on the inner rail 51 of the lower game board 30L on the inner back surface (bottom surface) of the inner groove 315, while the outer groove 316 The inner inner surface (bottom surface) is the outer rail 5 of the lower game board 30L. Spaced (floating) will be held in the posture, thus only the inner rail 51 of the lower game board 30L and thus receive the load of the upper game board 30H between. In the rail unit 50, the game ball (launch ball) launched from the game ball launcher is directly guided not by the inner rail 51 but by the outer rail 52. For example, the outer rail 52 is subjected to some deformation or the like. If it occurs, the influence on the trajectory of the launch ball is much greater than the case of the inner rail 51. Therefore, by adopting a configuration in which the load of the upper game board 30H is applied only to the inner rail 51 and is not applied to the outer rail 52 as described above, the outer rail 52 can be made less likely to be deformed.

  At this time, as described above, since the distance between the center in the width direction of the inner groove 315 and the center in the width direction of the outer groove 316 is equal to the distance between the inner rail 51 and the outer rail 52, as schematically shown in FIG. The inner rail 51 and the outer rail 52 can be fitted so as to be positioned at the center in the width direction of the inner groove 315 and the center in the width direction of the outer groove 316, respectively, and the width W315 of the inner groove 315 is equal to the outer groove 316. Therefore, the upper game board 30H and the lower game board 30L are relatively in the width W315 direction of the inner groove 315 (or the width W316 direction of the outer groove 316). When moving (displacement), the upper game board 30H and the lower game board 30L can move relative to each other only within the range in which the inner rail 51 can move in the width W315 direction within the inner groove 315. In other words, the relative movement between the upper game board 30H and the lower game board 30L in the direction of the width W315 of the inner groove 315 is regulated by the fitting structure of the inner rail 51 and the inner groove 315. On the other hand, the upper game board 30H and the lower game board 30L are relatively moved relative to each other in the width W315 direction of the inner groove 315 within the range in which the inner rail 51 can move in the width W315 direction in the inner groove 315. However, the outer rail 52 does not come into contact with both side surfaces of the outer groove 316, and is maintained in a posture with a space between both side surfaces of the outer groove 316. In other words, when the upper game board 30H and the lower game board 30L are relatively displaced in the board surface direction, one side surface of the outer groove 316 of the upper game board 30H and the outer rail 52 of the lower game board 30L are separated. In a non-contact state, one side surface of the inner groove 315 of the upper game board 30H and the inner rail 51 of the lower game board 30L are contacted preferentially. Therefore, for example, when the upper game board 30H is stacked on the lower game board 30L or after the work, there is some external force that shifts the upper game board 30H and the lower game board 30L along the board surface direction. When applied, this external force is transmitted (acts) only between the inner rail 51 and the inner groove 315, and is not transmitted (acts) between the outer rail 52 and the outer groove 316. The outer rail 52 is not affected and is not easily deformed.

  Note that the width W315 direction of the inner groove 315 or the width W316 direction of the outer groove 316 is itself a single direction (one direction) along a straight line, but the inner groove 315 and the outer groove 316 are the same as those described above. Since the inner rail 315 and the outer rail 52 are formed in a substantially partial annular shape, the width of the inner groove 315 and the outer groove 316 as a whole is generally determined by the width W315 and W316 directions. The direction of the entire circumference (360 °) is directed in a state parallel to the board surface of the board 30. Therefore, here, the width W315 direction of the inner groove 315 or the width W316 direction of the outer groove 316 is considered to coincide with the board surface direction of the game board 30.

  In the above-described configuration, as described above, the load on the upper game board 30H, that is, the external force in the direction of gravity, and the external force that works to shift the upper game board 30H and the lower game board 30L in the board surface direction are both the inner rail 51. Is transmitted (acted) only between the inner groove 315 and the inner groove 315, and the outer rail 52 is always inwardly separated from the outer groove 316 without contacting either the inner back surface (bottom surface) or both side surfaces ( It is designed to be held in position. That is, in the above-described configuration, as described above, the inner and outer grooves 316, 316 and the inner rail 51 and the outer rail 52 are fitted to each other so that the upper game board 30H and the lower game board 30L are relatively relative to each other in the board direction. Although the movement is restricted, more strictly speaking, the upper game board 30H is supported on the lower game board 30L because the upper game board 30H and the lower game board 30L are relatively relative to each other in the board direction. The movement is restricted only by fitting the inner rail 51 and the inner groove 315, and the fitting of the outer rail 52 and the outer groove 316 is not involved in either. In other words, as the inner rail 51 and the inner groove 315 are fitted for the purpose of support and regulation as described above, the outer rail 52 also protrudes with the same dimension as the inner rail 51, so that it is inevitably the upper side. Since the game board 30H will come into contact with (be particular about) the back side (lower side), the outer rail 52 will not come into contact with the outer rail 52 on either side as a clearance for preventing the outer rail 52 from coming into contact. It can also be said that the side grooves 316 are laid together.

(3) After that, components or members such as a main display unit 371, a variable display device unit 35, nails, various winning devices, etc., which will be described later, are attached to the front surface of the game board member 301, as shown in FIGS. A game board 30 is obtained.

In addition, a pair of opening and closing blades 60 are provided at the entrance of the lower start port 33b, and an open position for guiding the game ball and a closed position where the game ball is difficult to enter the lower start port 33b can be taken. The opening / closing blade 60 is driven by a solenoid SL1 disposed on the back side of the game board 30. In addition, a large winning opening (inlet of the accommodating portion) 61 is disposed below the lower start opening 33b. The special winning opening 61 will be described later. In the special winning opening 61, a ball detection switch SW1 is provided.

  A game ball enters the above-described general winning device 31, variable winning device 32 and first start winning device 33, and the detected ball is detected by a detection switch (a winning port switch, a count switch, an operating port switch, etc.) described later. Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15). In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. A number of nails are implanted in the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (instruments) are arranged.

  As shown in FIG. 4, the main display unit 371 has corners on the upper right corner that are right angles and whose opposite sides are oblique sides that extend from the upper left to the lower right. Is a part having a three-dimensional outer shape with a slight thickness in the front and rear as shown in FIG. ing. A flange 371F having a screw insertion hole is formed on the upper right rear side of the main display unit 371, and a screw insertion hole (not shown) is recessed in the lower right corner from the front side to the rear wall. ) And a screw insertion portion 371N having a substantially U shape in front view, and a screw is screwed into the flange 371F and the screw insertion portion 371N, so that the main display unit 371 is connected to the front surface of the game board member 301 as shown in FIG. It is fixed to the upper right part. The upper left upper surface portion of the main display unit 371 is formed so as to be inclined slightly downward to the lower left, and the center portion thereof is located at the tip of the outer rail 52 corresponding to the maximum flying portion of the game ball as shown in FIG. A return rubber 371R made of a rubber plate is attached on this portion as shown in FIG. The return rubber 371R hits and rebounds the game ball launched at a predetermined momentum or more. A display portion 371M is formed on the front surface of the main display unit 371. The display portion 371M has a front shape extending in an arc along the oblique side from the vicinity of the upper left end and adjacent to the screw insertion portion 371N, and is stepped into the inner depth. Has been.

  In the display unit 371M, four display devices 371A, 371B, 371C, and 371D are sequentially arranged so as to be arranged in an arc from the top. The first display device 371A from the top is made up of two LEDs on the left and right, and lights up in three ways by lighting only one or both of them, so that the probability of a big hit is low probability, medium probability and high probability Which one is displayed. The second display device 371B from the top is composed of several (7 to 9) LED segments and displays the types of special symbols. The display content of the second display device 371B from the top is also displayed by the decorative symbol display device. The third display device 371C from the top is composed of two left and right LEDs, and displays the number of reserved balls related to special symbols by combining these lighting states with a blinking state. A holding lamp 800a composed of four lamps arranged at the right end along the lower side of the decorative symbol display device 42 is disposed at the bottom of the frame 421 (see FIGS. 4 and 10). The number of holding balls related to the special symbol is also displayed by the holding lamp 800a. The fourth display device 371D from the top is similarly composed of several LED segments and displays the number of rounds per unit. The fifth display device 371E from the top is composed of a total of 9 LEDs, 6 in the left column and 3 in the right column. Of these, the 3 LEDs in the upper left are lit in blue or red to indicate hit / miss. It is a normal symbol display device, and three LEDs on the right and three on the lower left display the number of reserved balls related to the normal symbol by a combination of a lighting state and a blinking state.

  The main display unit 371 is fixedly attached to the front surface of the game board member 301 so as to cover the main display unit mounting notch 301C from the front side. A connector is provided on the rear surface of the main display unit 371. The connector is received in the main display unit mounting notch 301C and is inserted into the backing member 302 that communicates with the back side of the main display unit mounting notch 301C. A wiring from the control device on the back side of the game board 30 is connected to the main display unit 371 through the hole 323R.

  At this time, the main display unit mounting cutout 301C is a cutout in which the right edge portion of the game board member 301 is recessed in a substantially U-shape. For example, when removing the backing member 302 from the game board member 301, The main display unit 371 can be easily removed from the game board member 301 by removing it from the main display unit mounting notch 301C even when the wiring is connected, if the screw fixing at the flange 371F and the screw insertion portion 371N is released. In addition, when re-attaching to the game board member 301, it can be easily attached by fitting it into the main display unit attachment notch 301C from the side with the wiring connected, and thus, for example, the game board When only the member 301 is replaced with a new one or a different one, the removal and attachment work becomes easy. To have.

  By making the main display unit mounting notch 301C substantially U-shaped as described above, the main display unit 371 can be easily attached and detached, so that, for example, the game board member 301 can be easily replaced and recycled as described above. Although it is advantageous also in the above, it becomes advantageous also in, for example, removing and cleaning only the game board member 301 because the game board member 301 can be easily attached and detached. The game board member 301 is easily soiled by the contact of the game ball, and this dirt is particularly noticeable in the resin game board member 301. Therefore, it is desirable that the game board member 301 has a structure that can be easily cleaned.

  The special symbol display device variably displays a special symbol as identification information with the winning of the first start winning device 33 as a trigger, and the decorative symbol display device 42 fluctuates a decorative symbol corresponding to the variation display of the special symbol. The normal symbol display device variably displays the normal symbol with the passage of the second start winning device 34 as a trigger.

  The special symbol display device is composed of nine LED segments of the first display section in the display device 371A, which will be described later, and the display content is controlled by a main control device 261 described later.

  The normal symbol display device includes two lamps for normal symbols (hereinafter also referred to as a first lamp and a second lamp) arranged in a display device 371B described later. In this embodiment, the first lamp for ordinary symbols has an outer shape of “◯”, while the second lamp is provided adjacent to the right side of the first lamp, and the outer shape of the first lamp is “ X ”shape. In the normal symbol display device, for example, the display symbols (ordinary symbols) by the first and second lamps change every time the game ball passes through the second start winning device 34, specifically, the first and second lamps. Are alternately turned on, and the lower start port 33b of the first start winning device 33 is activated (opened) for a predetermined time when stopped by the first lamp. The number of times that the game ball has passed through the second start winning device 34 is held up to a maximum of 4 times, and the number of times that the game ball is held is displayed on the hold lamp 801a. The first and second lamps may be a plurality of display units that are variably displayed on a part of the decorative symbol display device 42.

  As shown in FIGS. 4, 5, 10, and 11, the variable display device unit 35 is disposed at the center of the game area and is a large-sized accessory that occupies a large area in the game area. Also referred to as an accessory unit or center accessory. The variable display device unit 35 includes a decorative symbol display device 42 as a display unit in the center, and is configured to surround the upper side portion, the lower side portion, the left side portion, and the right side portion of the decorative symbol display device 42 with a center frame 43. Has been.

  The center frame 43 is a frame-like member that includes a substantially horizontally long rectangular opening in which the decorative symbol display device 42 is disposed, and a flange 43F having a screw hole is provided on the outer periphery. It is fixed on the game board 30 from the front side by screws.

  As shown in FIG. 10, on the left side of the center frame 43, the upper and lower ends have a substantially C-shape in front view with the upper and lower ends extending slightly to the upper right and the lower right, respectively, and a ball passage through which game balls flow down. A left warp passage portion 43L is formed, and a ball entry portion 431L and a sleeve opening portion 432L are formed at the upper right end portion and the right lower end portion of the left warp passage portion 43L, respectively. On the right side of the center frame 43, there is formed a right warp passage 43R that is symmetrical to the left warp passage 43L. On the lower side of the center frame 43, there is formed a stage 43S that is rounded downward as viewed from the front and slightly raised at the center so that the game ball can roll back and forth to the left and right. A ball entrance is provided on the inner back side of the central portion, and a ball passage is formed from the ball entrance to the ball outlet on the front surface through the center of the stage 43S.

  A large number of nails are planted above the center of the upper end of the center frame 43 so as to be arranged in a mountain shape in front view at intervals smaller than the diameter of the game balls. First, the nails arranged in a mountain shape are distributed to the left and right, and most of the game balls that flow down to the lower left flow down on the left warp passage 43L and flow down to the lower left of the center frame 43. However, some of the game balls enter the entrance portion 431L, flow down in the left warp passage portion 43L, and are discharged onto the stage 43S from the sleeve opening portion 432L. On the other hand, most of the game balls that have been distributed to the right by the nail above the center frame 43 and flowed down to the lower right flow down on the right warp passage portion 43R and to the right of the center frame 43, as in the case of the left side. The ball flows downward, and a part of the game balls passes through the right warp passage 43R and is discharged onto the stage 43S. The game balls guided from both sides to the stage 43S through the left warp passage 43L or the right warp passage 43R roll so as to reciprocate left and right on the stage 43S, and many of them fall forward on the way. A part of the ball enters the ball entrance at the center, and the ball is thrown forward from the ball exit at the front and falls, and then enters the first starting prize-winning device 33 directly under the high probability. Become.

  The decorative symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device described later. On the decorative symbol display device 42, for example, symbols as identification information are displayed at three locations, upper, middle, and lower. These symbols are scrolled and variably displayed on the decorative symbol display device 42. In this embodiment, the decorative symbol display device 42 (liquid crystal display device) is provided with a large liquid crystal display having a size of 10 inches or 12 inches, for example.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated in an open state and a normal closed state in which a game ball is easy to win in a big win. However, the specific configuration will be described later. In short, when the special symbol display device is in a specific display mode (when the confirmed symbol after the decoration symbol display device 42 is stopped is a combination of specific symbols set in advance), the special gaming state is Occur. Then, the variable winning device 32 is in a ball receiving state and allows a game ball to be won. Specifically, the ball receiving state of the variable winning device 32 is repeatedly released a predetermined number of times, with a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winnings taken as one round. The number of times that the game ball has passed through the first start prize-winning device 33 is held up to 4 times, and the number of times of holding is lit and displayed on the hold lamp 800a. Note that the hold lamp 800a may be configured to be variably displayed on a part of the decorative symbol display device 42.

  The game board 30 is attached and fixed to the inner frame 12 so as to be fitted from behind. At this time, in the game board 30 of this embodiment, the first positioning boss 305T and the fourth positioning boss 305L of the backing member 302 are guided to the approximate mounting position on the pachinko machine 10 main body side, and the lower surface of the game board member 301 When the front surface comes into contact with the inner frame 12, the vertical position and the front / rear position of the game board 30 relative to the main body of the pachinko machine 10 are determined.

  27 to 29 are schematic views showing a state in which the game board 30 is attached to the inner frame 12. As shown in the figure, the inner frame 12 (indicated by a chain line in the figure) is configured in a frame shape that supports the peripheral portion (four peripheral portions) of the game board 30, and thus a substantially rectangular portion corresponding to the game board 30. Most of the front panel 12F is open, and below the open part is a front panel 12F that extends to the lowest part including the lower plate unit 13. As shown in FIG. 29, the front surface of the front panel 12F is located on the same plane as the board surface of the game board 30, the thickness is slightly larger than the thickness of the game board 30, and the upper end surface is a bearing surface that supports the game board 30. 12B. As shown in FIGS. 27 to 29, on the right side portion of the front surface of the front panel 12F, the lower end portion of the outer rail 52 located on the upper left side from the game ball launching device (not shown) disposed on the lower right end portion is provided. The firing rail 38R is disposed and fixed so as to tilt upward. The upper right end portion of the front surface of the front panel 12F bulges forward one step as shown in FIG. 29, extends upward in a generally rectangular shape when viewed from the front, as shown in FIG. The right front wall 12 </ b> R is integrally formed so as to be angularly dropped (notched) along the arc. The left end of the right front wall 12R is located to the right of the out port 36 of the game board 30 and slightly to the left of the right end of the lower extension portion 301E of the game board member 301. On the other hand, the left upper end of the front surface of the front panel 12F bulges forward (not shown) as in the case of the right front wall 12R (not shown). As shown in FIG. Accordingly, the left front wall 12L is integrally formed so as to extend upward to a position close to the lower end of the outer rail 52. The right end of the left front wall 12L substantially coincides with the position of the lower right end of the outer rail 52 of the game board 30 and is positioned slightly to the right of the left end of the lower extension 301E of the game board member 301. Accordingly, the right front wall 12R and the left front wall 12L have both ends located at positions slightly closer to the center than both ends of the lower extension portion 301E in the game board member 301 and fly from the launch rail 38R to the outer rail 52. A notch having a sufficient width that does not interfere with the playing ball is formed in the center.

  The central portion of the lower end of the front peripheral wall portion 304B of the lower piece 302B of the backing member 302 of the game board 30 is opened as described above, and the lower extension portion 301E of the game board member 301 is substantially spaced from the open portion. It has been inserted. At this time, as shown in FIG. 27, the lower end of the lower extending portion 301E is formed slightly longer so as to extend slightly below the lower end of the backing member 302. Therefore, the lower end of the lower extension 301E of the game board member 301 is the lowermost end of the entire game board 30. As shown in FIGS. 27 and 29, the game board 30 is supported by the inner frame 12 as a support surface. 12B, the lower end portion 301E of the lower extension portion 301E of the game board member 301 is supported by being abutted on the support surface 12B, and on the right and left sides of the lower extension portion 301E, Gaps 39R and 39L are formed between the bearing surface 12B and the lower end surface of the backing member 302, respectively. Note that the contact position T11 between the lower extension 301E of the game board member 301 and the support surface 12B of the inner frame 12 is indicated by a cross in the drawing for the sake of convenience. Surface contact between surfaces.

  On the other hand, as shown in FIGS. 28 and 29, the game board member 301 of the game board 30 is slightly ahead of the front end of the backing member 302, that is, the extended end of the front peripheral wall portions 304T, 304B, 304L, 304R. It has a thickness that protrudes. In other words, the front peripheral wall portions 304T, 304B, 304L, and 304R of the backing member 302 are formed so as to extend to a position that does not reach the front surface of the game board member 301. Therefore, when the game board 30 is pressed against the inner frame 12 from the rear, the front surface of the game board member 301 of the game board 30 comes into contact with the back side surfaces of the right front wall 12R and the left front wall 12L of the inner frame 12 to play the game. The front and rear positions of the board 30 are determined, and on the right side and the left side of the lower extension portion 301E of the game board member 301, the back side surface of the right front wall 12R and the left front wall 12L of the inner frame 12 and the front surface of the backing member 302, Gaps 41R and 41L are formed between the extended end surface of the front peripheral wall portion 304B of the lower piece 302B. Note that the contact positions T12 and T13 between the front surface of the game board member 301 and the back side surfaces of the right front wall 12R and the left front wall 12L of the inner frame 12 are indicated by X in the drawing for the sake of convenience. The contact here is surface contact between the surfaces.

  As described above, the game board 30 is positioned and attached to the inner frame 12 by contact with the game board member 301 in both the vertical position and the front-rear position, and the backing member 302 contacts the inner frame 12. It has a configuration that does not touch and is not involved in positioning. At this time, it is assumed that the game board member and the backing member are formed so as to be on the same surface on the lower surface and the front surface, and both the game board member and the backing member are simultaneously brought into contact with the inner frame on the lower surface and the front surface. In such a case, it is difficult to configure the two surfaces so that they are completely and exactly on the same plane, and avoid misalignment between the two due to errors in the molding and assembly processes. hard. Therefore, which of the game board member and the backing member abuts against the inner frame is not constant, and therefore the relative position between the game board member and the inner frame is not constant. Since the game ball launched from the launching device is guided to the game area along the front surface of the game board member and flows down, the deviation of the relative position of the game board member with respect to the inner frame directly affects the trajectory of the game ball. Become. In particular, the launch ball emitted from the launch rail first lands on the outer rail on the game board member and is guided upward along the outer rail to be guided to the game area. At this time, the game board member If it is displaced in the vertical direction or the front-rear direction with respect to the inner frame, the landing point of the launch ball on the outer rail will also shake in the vertical direction or the front-rear direction. On the other hand, in the game board 30 of the pachinko machine 10, the lower end of the game board member 301 protrudes slightly below the lower end of the backing member 302 as described above, and the front surface of the gaming board member 301 is the backing member 302. Since it is configured to protrude slightly below the front surface of the inner frame, even if some misalignment occurs between the game board member 301 and the backing member 302 due to errors in the molding or assembly process, the inner frame 12, the game board member 301 can always contact with the game board member 301 in both the vertical position and the front-back position. In other words, by slightly projecting the game board member 301 downward and forward from the backing member 302, a slight positional shift generated between the game board member 301 and the backing member 302 is absorbed, and thereby the intention is made. Therefore, the backing member 302 is not in contact with the inner frame 12 and involved in positioning. Therefore, the relative position of the board surface of the game board 30 with respect to the inner frame 12 is not shifted, and the shot ball is stably landed on the outer rail 52 without being shaken, and the game board member 301 is guided to the game area. In other words, it is possible to always maintain the normal position stably and accurately without deviating the trajectory of the launch ball.

  Also, for example, if the lower end of the backing member abuts against the inner frame and the gaming board is supported on the inner frame by the backing member, the gaming board may be compared to the case where the gaming board member is supported. It is easy for the posture to change due to slanting. In addition, if a gap is formed between the lower end of the game board member and the inner frame, a fraudulent operation may be performed on the back side of the game board by entering a thin plate-like unauthorized tool or the like through the gap from the front side. There is also. On the other hand, in the game board 30 of the pachinko machine 10, as described above, the lower end surface of the game board member 301 (lower extension portion 301E) is always supported by being in contact with the support surface 12B of the inner frame 12. Therefore, the game board 30 can be always stably installed in a correct posture, and the lower end surface of the game board member 301 (lower extension portion 301E) and the bearing surface 12B of the inner frame 12 are supported. It is possible to make it difficult to form a gap that allows an unauthorized tool or the like to enter. In this case, as described above, the gaps 39R and 39L are formed on both sides of the lower extension portion 301E. However, the lower extension portion 301E is located immediately below the first start winning device 33 and is particularly illegal. It is particularly effective to make it difficult for gaps to be formed in this part because it is a part where tools and the like are likely to enter.

  In the above mounting structure, the lower extension 301E of the game board member 301 is continuously in contact with the inner frame 12 at the center of the lower end of the game board 30, and the backing member 302 is not interposed therebetween. Therefore, the launch ball can be delivered from the launch rail 38R onto the game board member 301 without any trouble.

  Further, according to the mounting structure described above, the gaming board 30 is surrounded by the opaque backing member 302 that is generally black except for the lower extending portion 301E and the left extending portion 301F at the periphery of the transparent gaming plate member 301. More specifically, the backing member 302 covers the area around the center portion corresponding to the game area on the back surface of the game board 30, and the front peripheral wall portions 304T, 304B, 304L, and 304R are in front. The ridges of the game board 30 are substantially all (the ridges of the ridges of the game board 30 that are constituted by the lower extension part 301E and the left extension part 301F at the front peripheral edge. Are formed of the backing member 302, so that the game board member 301 is not only effectively protected from external force but also light from various light emitting means disposed on the game board 30. Leaking around is effectively suppressed, thus light up, for example, unnecessary portions obtained effect on one emission effect that it is possible to not be illuminated.

(Back view of pachinko machine)
Next, the configuration of the back surface of the pachinko machine 10 will be described. FIG. 30 is an exploded perspective view showing the configuration of the back surface of the pachinko machine 10.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. On the back surface of the pachinko machine 10 (actually, the back surface of the inner frame 12 and the game board 30), various control boards are arranged so as to be lined up and down, left and right, or stacked in front and back, A game ball supply device (payout mechanism) for supplying game balls, a resin back cover (protective cover), and the like are attached. In this embodiment, various control boards are divided into three mounting bases to form three control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. . In this case, the main control device 261 composed of a main control board, a power supply monitoring board, a board box that accommodates these boards, and a sealing unit that seals the board box is unitized into one unit, and the display control board and the display control board A display control device 45 composed of a substrate box for housing the decorative design display device 42 and a sub control device 262 composed of a sub control substrate and a substrate box for housing the sub control substrate are mounted on an outer packaging member 82 to be described later. A payout control board 311 comprising a payout control board, a board box (payout control board case) for housing the payout control board, and a sealing unit for sealing the board box; a power supply board; a launch control board; It consists of a board box (power supply / launch control board case 203A) that houses these boards. It is unitized by mounting a power-firing controller in a single mount. Here, for convenience, each unit will be referred to as a “first control board unit 201”, a “second control board unit 202”, and a “third control board unit 203” in the order described above.

  Further, the payout mechanism and the back cover (protective cover) are also integrated with the third control board unit 203, and the resin part is generally referred to as a back pack. Also referred to as “pack unit 203”. The detailed configuration of each unit 201 to 203 will be described later.

  As will be described later, the first control board unit 201 is configured to be able to be attached without using a fastener such as a screw or a tool, although it is necessary to release the sealed state with a tool when removing the first control board unit 201. The second control board unit 202 and the back pack unit 203 are configured to be detachable without using any tools or the like in units. Further, in addition to this, each of the units 201 to 203 has a structure in which a support shaft portion is provided in part and can be opened and closed with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  The first control board unit 201 described above has a main control board that controls the progress of the game and a power supply monitoring board that manages power supply monitoring. The main control board and the power monitoring board are housed in a board box made of a transparent resin material or the like. The board box includes a box base having a substantially rectangular parallelepiped shape and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other by a sealing unit so that the board box cannot be opened. Is sealed.

  Any configuration can be applied to the sealing unit as long as the box base and the box cover are connected so as not to be opened, and the sealing process by the sealing unit prevents unauthorized opening after the sealing. Even if an unauthorized opening is performed, such a situation can be detected early and easily.

  The second control board unit 202 includes a display control device 45 that controls display of the decorative symbol display device 42 according to an instruction from the main control board, and a sub control board that controls sound lamp control according to an instruction from the main control board. The display control device 45 includes a decorative symbol display device 42 and a display control board as a unit, is accommodated in a board box made of a transparent resin material or the like, and is attached to the back side of an outer packaging member 82 described later.

The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. The power failure signal SG1 is output to the main controller 261 and the payout controller 311. By the output of the power failure signal SG1, the main controller 261 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 541 outputs a voltage of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Is maintained at a normal value. Therefore, the main controller 261 and the payout controller 311 can normally execute and complete the NMI interrupt process.

The RAM erase switch circuit 543 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main controller 261 and the payout controller 311 when the RAM erase switch is pressed. Note that transmission of a signal to the payout control device 311 is performed via the main control device 261.
When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main control device 261 and the payout control device 311 clear the respective backup data.

  The reset circuit 544 is a circuit that outputs a reset signal in order to initialize the main control device 261, the payout control device 311, the sub control device 262, and the display control device 45. The reset signal from the reset circuit 544 is directly given to the main control device 261, but the payout control device 311, the sub control device 262, and the display control device 45 are connected via the power supply device 313. It has come to be given.

  Here, the display contents of the special symbol display device, the normal symbol display device, and the decorative symbol display device 42 will be described. In the pachinko machine 10 of the present embodiment, the special symbol displayed on the special symbol display device as a symbol for showing the occurrence of the jackpot to the player, and the decorative symbol displayed on the decorative symbol display device 42 are two. Types are provided. The decorative symbol is a symbol that changes in synchronization with the special symbol. The decorative symbol starts changing at the same time (or almost at the same time) as the special symbol starts to change, and at the same time (or almost at the same time) as the special symbol changes. To stop the fluctuation. This decorative design is provided in order to provide a player with a variety of display effects so that the player is not bored.

  First, the display contents of the special symbol display device will be described. The special symbol variation display is expressed by a change in the lighting pattern of the nine LED segments. The variation display of the special symbol is started based on winning of the game ball to the start winning device 33, and the variation display of the special symbol is simultaneously stopped after a certain time. After the stop, a lighting pattern indicating a big hit or a lighting pattern indicating a loss is displayed. In the case of a loss, a variation display is performed again based on winning to the start winning device 33. The number of times that the game ball has won the start winning device 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed on the hold lamp 800a of the special symbol hold display device 800.

  Next, display contents of the decorative symbol display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol columns Z1 to Z3 are displayed in three display areas divided into an upper stage, a middle stage, and a lower stage. These decorative symbol rows Z1 to Z3 are scroll-displayed from right to left. The decorative symbol is composed of, for example, a main symbol composed of numbers “1” to “9” and a sub symbol smaller than the main symbol, and a symbol row of the decorative symbol is formed by each of the main symbol and the sub symbol. In each symbol row formed with decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub-designs are arranged between the main symbols. When a winning to the start winning device 33, that is, a start winning occurs, the decorative symbol is displayed in a variable manner, and the variable display is stopped after a lapse of a certain time according to the changing pattern. 3 nine decorative symbols are displayed as a display result. In the variable display won in the big win lottery, the display control device 45 controls the three main symbols so that they stop on a vertical or diagonal straight line among the nine decorative symbols. The jackpot is indicated. On the other hand, in the variable display out of the big hit lottery, the display control device 45 controls the game so that three identical main symbols do not stop vertically or diagonally among the nine decorative symbols. The person is shown an outbreak.

  Next, the display contents of the normal symbol display device will be described. The normal symbol variation display is expressed by alternately lighting the first lamp (appearance is ◯ shape) and the second lamp (appearance is X shape). The normal symbol variation display is started on the condition that the game ball passes through the second start winning device 34, and the regular symbol variation display stops after a certain period of time. And when it stops by a 1st lamp | ramp, it is comprised so that the 1st start prize-winning apparatus 33 may be in an operation state only for predetermined time (open | released). The number of times that the game ball has passed through the second starting prize-winning device 34 is held up to a maximum of 4 times, and the number of times that the game ball is held is displayed on the hold lamp 801a of the normal symbol hold display device 801.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to set up a jackpot lottery or a symbol display setting of a special symbol display device. Specifically, a counter group related to the special symbol and a counter group related to the normal symbol are provided. First, a counter group related to special symbols will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the special symbol display device, and the special symbol display device when the special symbol display device is out and fluctuates. Stop pattern selection counter C3 used for selection of stop patterns (corresponding to reach lottery for reaching or completely disabling in the variation of decorative symbols), and initial values used for setting initial values of the jackpot random number counter C1 A random number counter CINI1 and variation type counters CS1 to CS3 for determining a type used for variation pattern selection are provided.

  Here, the variation pattern means each pattern (form) in a case where features having common features of variation display are divided.

  Each of the counters C1 to C3, CINI1, CS1 to CS3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 700 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game to the start winning device 33 is performed. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 are stored in accordance with the winning timing of the ball.

Next, the specific contents of each counter will be described in detail.
The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the big hit random number counter C1 (value = 0 to 738), and is updated once every timer interruption and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “373, 727” There are 14 random numbers that are big hits at high probability, and the values are “59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 577, 631, 683, 733”. is there. High probability means a state in which a special symbol combination is a jackpot due to the combination of a specific symbol that is a predetermined probability variation symbol and the subsequent jackpot probability has increased as added value, so-called probability change. Time (when the probability is low) refers to a case where the probability variation state is not such.

  The jackpot symbol counter C2 determines a symbol at the time of a jackpot when the special symbol display device stops changing the special symbol. For example, the jackpot symbol counter C2 is incremented by one within a range of 0 to 4, and the maximum value (that is, 4). After reaching this value, it returns to 0. For example, when the value of the jackpot symbol counter C2 is “0” or “1”, nine LED segments are stopped at a specific lighting pattern, and the combination of stop symbols in this case is a non-specific symbol (normally Of jackpot symbol).

  When the value of the jackpot symbol counter C2 is “2”, “3”, “4”, the nine LED segments stop in a specific lighting pattern different from the above, and the stop symbol of this case The combination means a specific symbol (probability variation symbol).

  The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

  The stop pattern selection counter C3 is, for example, incremented by 1 in the range of 0 to 238, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the special symbol variation display is configured to be expressed by nine LED segments. Therefore, in the case of the special symbol, there is no concept of reach, and a stop pattern corresponding to reach is designated as a stop pattern selection counter C3. It is decided to decide. On the other hand, in the case of a decorative symbol, since three decorative symbols are stopped, there is a reach. Therefore, in the case of a decorative design, the reach lottery is determined by the stop pattern selection counter C3. That is, in the case of a decorative design, after the reach has occurred, the final stop symbol is shifted by one shift before and after the reach symbol, and the stop symbol is stopped before and after the reach symbol. It is decided to draw “reach other than front / rear off” to stop and “complete out” that does not cause reach. For example, the stop pattern selection counter C3 = 0 to 201 corresponds to complete detachment, the stop pattern selection counter C3 = 202 to 208 corresponds to anteroposterior detachment reach, and the stop pattern selection counter C3 = 209 to 238 lies other than detachment anteroposterior. Applicable.

  Here, “reach” refers to a combination of symbols that stop before the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts changing display, and the combination of symbols that stop first is the same symbol (in a decorative symbol having a plurality of effective lines). A combination of jackpot symbols, suggesting to the player that the jackpot will be a big win depending on the display result of the symbols that are the same symbol on any active line) and satisfy the jackpot condition Is a display that makes a player expect the game, and is a type of entertainment production. An interesting effect is that a predetermined symbol represented by reach is displayed on the display screen of the decorative symbol display device 42 in the middle of variable display, a specific sound is output from a speaker, or a vibration motor is used. This is an effect that causes the player to expect that the display result after the change display will be a big hit with the change display, such as vibrating the game ball launch handle 18.

  The stop pattern selection counter C3 is periodically updated (once every timer interruption in this embodiment) and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball is won by the start winning device 33.

The variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). For example, the variation type counter CS3 is incremented by 1 within a range of 0 to 162, for example, and reaches a maximum value (that is, 162) and then returns to 0.
The variation type counter CS1 determines a rough symbol variation mode such as the reach type such as normal reach, super reach, premium reach, etc., and the variation type counter CS2 further refines the symbol such as normal reach A, normal reach B, etc. The variation mode is determined, and the variation type counter CS2 determines, for example, the addition / subtraction of the variation time in the case of a slip stop variation. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 to CS3.

  The counters CS <b> 1 to CS <b> 3 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the counters CS1 to CS3 are acquired when determining the variation pattern at the start of variation of the special symbol by the special symbol display device and the decorative symbol display device 42.

  Next, a counter group related to normal symbols will be described. The counter group related to the normal symbol includes a winning random number counter C4 used for winning lottery and an initial value random number counter CINI2 used for setting an initial value of the winning random number counter C4.

  The hit random number counter C4 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. The counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 701 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, the second start winning device 34 is provided. The value of the hit random number counter C4 is stored in accordance with the passing of the game ball.

  Next, the specific contents of the winning random number counter C4 and the initial value random number CINI2 will be described in detail. The winning random number counter C4 is, for example, incremented by 1 in the range of 0 to 250, and returns to 0 after reaching the maximum value (that is, 250). When the winning random number counter C4 makes one round, the value of the winning initial value random number counter CINI2 at that time is read as the initial value of the winning random number counter C4. The initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the winning random number counter C4 (value = 0 to 250), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The winning random number counter C4 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the second start winning device 34. The number of random number values hit by the hit random number counter C4 is 149, and the value is “5 to 153”.

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, the big hit random number counter C1, the stop pattern selection counter C3, the hit random number counter C4, and the variation type counters CS1 to CS3 are all different prime numbers and are not synchronized in any case. It is desirable to leave.

The details of each control process executed by the MPU 501 in the main controller 261 will not be described here.
However, in summary, as described above, by winning the start winning device 33, the main control device 261 performs a lottery with a predetermined probability, and when winning, it shifts to a special gaming state. Thus, the variable winning device 32 enters a winning ball receiving state.

(Variable winning device and collection unit)
In this embodiment, the variable winning device 32 is configured as follows.
The basic configuration of the variable winning device 32 is to house a winning ball from a large winning opening 61 having a width that allows a plurality of gaming balls to pass in the lateral direction of the game board 30 in a housing portion (not shown). A detection sensor (not shown) is detected from a discharge portion provided in the storage portion.

  Then, a start winning device 33 (33a and 33b: see FIGS. 4 and 10) for entering a game ball flowing down the flowing space between the window portion 101 and the game board 30 into the game area of the game board 30 is provided. A winning lottery with a predetermined probability is performed by the main control device 261 by entering the starting prize winning device 33, and the game state is shifted to the special game state by the corresponding lottery. In the special game state, At least once, the variable winning device 32 is switched from the non-ball receiving state to the ball receiving state, and in the ball receiving state, a predetermined number of winning balls received from the large winning opening 61 are received in the receiving portion by the detection sensor. A predetermined number of award balls are paid out by detecting the above.

(Function)
As described above, the pachinko machine 10 includes a gaming machine main body provided with a launching device, and a gaming board 30 attached to the gaming machine main body from the back side. A game board member 301 made of a resin having a light transmitting property, and a backing member 302 fixed to a part of the back surface of the game board member 301, wherein the backing member 302 includes the game board member 301. The front peripheral wall portions 304T, 304B, 304L, and 304R are provided as the extending portions extending forward along the end surface of the plate member 301, and the front peripheral wall portions 304T, 304B, 304L, and 304R are arranged around the game plate member 301. When the game board 30 is attached to the inner frame 12 on the side of the game machine main body, most of the game board parts (except for the lower extension part 301E and the left extension part 301F) are protected. The front surface of 301 and the mounting surfaces of the inner frame 12 facing the game board member, that is, the back side surfaces of the right front wall 12R and the left front wall 12L, contact the front and back of the game board 30 with respect to the game machine body. The position is determined.

  According to the configuration of the pachinko machine 10, since at least a part of the back surface and the end surface of the game board member 301 is covered with the backing member 302, the pachinko machine 10 receives some external force during handling or standing in the manufacturing process of the pachinko machine 10. Even in this case, the game board member 301 is protected from this external force by the backing member 302 and is not easily damaged.

  At this time, if the front and rear positions of the game board with respect to the gaming machine main body are determined by the extension end of the extending portion of the backing member coming into contact with the gaming machine main body, the gaming plate member and the backing member If the assembling condition of the game board is not strictly constant and the relative position in the front-rear direction is slightly shifted, the front-and-rear position of the board surface (front face) of the game board with respect to the gaming machine main body will also be displaced. Accordingly, the trajectory in which the played game ball (launch ball) is guided to the game area is also shifted somewhat.

  On the other hand, according to the configuration of the pachinko machine 10, when the game board 30 is attached to the game machine body, that is, the inner frame 12, the front surface of the game board member 301 and the attachment surface of the inner frame 12, that is, the right front wall 12R and the left Since the front and rear positions of the game board 30 with respect to the gaming machine main body are determined by contacting the back side surface of the front wall 12L, when the game board 30 is attached to the inner frame 12, the backing member 302 is extended. The extension ends of the front peripheral wall portions 304T, 304B, 304L, and 304R, which are parts, do not reach the inner frame 12, so even if there is a shift in the relative position between the game board member 301 and the backing member 302 in the front-rear direction. The board surface of the game board 30 is positioned accurately in the front-rear position with respect to the gaming machine main body without being affected by this deviation, and as a result, the fired ball is stably placed in the game area. It has become as to be guided in such orbit.

  Further, since the front surface of the game board member 301 projects forward from the extended ends of the front peripheral wall portions 304T, 304B, 304L, 304R, the game board 30 can be effectively attached to the game machine main body with a simple configuration. That is, when the game board member 301 is attached to the inner frame 12, the front surface of the game board 30 is in contact with the attachment surface of the inner frame 12, that is, the back side surfaces of the right front wall 12R and the left front wall 12L. Can be determined.

  Also, a lower extension 301E, which is a part of the lower end of the game board member 301, extends downward from the lower end of the backing member 302, and the game board 30 is attached to the inner frame 12 on the game machine main body side. When attaching, the lower end of the lower extension 301E abuts against the support surface 12B of the inner frame 12, so that the vertical position of the gaming board 30 relative to the gaming machine body is determined. Even if the relative position in the vertical direction between the member 301 and the backing member 302 is misaligned, the board surface of the gaming board 30 is accurately positioned with respect to the gaming machine body without being affected by this misalignment. As a result, the launch ball is stably guided to the game area in an accurate trajectory. Further, it is difficult to form a gap between the lower end of the lower extension portion 301 </ b> E and the inner frame 12 that allows an unauthorized tool or the like to enter.

  In addition, since the lower extension portion 301E that is a contact portion with the inner frame 12 at the lower end portion of the game board member 301 is located below the first starting prize-winning device 33, in particular, the entry of unauthorized equipment or the like It is difficult for a gap to be formed at a site where it is easy to achieve.

  Further, a concave portion is formed as a recessed portion in the lower center portion of the back surface of the backing member 302 which is one of the lower end central portion on the back surface of the backing member 302 and the front surface of the ball assembly plate disposed on the back side of the backing member 302. An entrance surface portion 318B is formed, and a projection corresponding to the recess surface portion 318B is formed on the front surface of the other spherical assembly plate. Since the collective plate is attached, for example, when trying to enter an unauthorized tool from below between the backing member 302 and the ball collective plate, the protrusion is located on the entry path. Is difficult to enter due to the protrusion.

  The entire backing member 302 basically has a configuration in which the front side surface (front side surface) is a wall surface, the back side (rear side) is opened, and lattice ribs are formed in the open space. Since the rear side surface (rear side surface) is a wall surface in the lower end central portion of 302 (lower piece 302B), the front side (front side) is opened, and a grid-like rib is formed in the open space. In the center of the lower end where unauthorized tools and the like are likely to enter, the backing member 302 (lower piece 302B) and the ball assembly plate are in contact with each other without any gap so that the unauthorized tools cannot easily enter.

  Further, as shown in FIG. 25, the pachinko machine 10 has a rail unit 50 having an inner rail 51 and an outer rail 52 for guiding a game ball launched from a launching device, and a game guided by the rail unit 50. In a configuration including a game board 30 having a game area in which a ball flows down on the front surface, a single game board (upper game board) 30H is different from the upper game board 30H (lower game board). An inner groove 315 and an outer groove 316 are provided on the back surface as rail fitting portions that can be fitted to at least a part of the 30L rail unit 50, and the inner groove 315 and the outer groove 316 of the upper game board 30H and the lower game board are provided. By fitting the inner rail 51 and the outer rail 52 of 30L, relative movement in the board direction between the upper game board 30H and the lower game board 30L is restricted. And it has a configuration.

  According to the configuration of the pachinko machine 10 described above, when a plurality of game boards 30, that is, for example, the upper game board 30H and the lower game board 30L shown in FIG. By fitting the inner groove 315 and the outer groove 316, which are 30H rail fitting portions, with at least a part of the inner rail 51 and the outer rail 52 of the lower game board 30L, the upper game board 30H and the lower game are combined. By restricting relative movement in the board surface direction with the board 30L, the game boards 30H and 30L are restrained from being displaced along the board surface direction, whereby a plurality of game boards 30 can be stably stacked. It is like that. At this time, in the case of a game board made of resin, the rail and the game board are easily slipped and displaced, but like the pachinko machine 10, the inner groove 315 and the outer groove 316 and the inner rail 51 and the outer rail 52 are fitted. As a material of the game board 30, rails are secured while ensuring stability when stacking a plurality of game boards 30 by suppressing relative displacement in the board surface direction by restricting relative movement. Any material can be used without considering the degree of slipperiness with respect to.

  When the upper game board 30H is stacked on the lower game board 30L, the inner back surface (bottom face) of the outer groove 316 of the upper game board 30H and the outer rail 52 of the lower game board 30L are not in contact with each other. Since the inner back surface (bottom surface) of the inner groove 315 of the upper game board 30H and the inner rail 51 of the lower game board 30L are preferentially brought into contact with each other, the upper game board 30H is located within the inner groove 315. The inner surface (bottom surface) of the outer groove 316 is spaced from the outer rail 52 of the lower game board 30L while being supported on the inner surface 51 of the lower game board 30L by the inner surface (bottom surface). Therefore, only the inner rail 51 of the lower game board 30L receives the load of the upper game board 30H. As a result, the load of the upper game board 30H is applied only to the inner rail 51, and the influence on the trajectory of the shot ball is directly large, and the load is not applied to the outer rail 52, so that deformation or the like is less likely to occur. Yes.

  Also, when the upper game board 30H and the lower game board 30L are relatively displaced in the board surface direction, one side surface of the outer groove 316 of the upper game board 30H and the outer rail 52 of the lower game board 30L come into contact with each other. In this state, the one side surface of the inner groove 315 of the upper game board 30H and the inner rail 51 of the lower game board 30L come into contact with each other preferentially, so that, for example, the upper game on the lower game board 30L When any external force is applied that causes the upper game board 30H and the lower game board 30L to be displaced along the board surface direction during or after the stacking operation of the board 30H, the external force is applied to the inner rail 51 and the inner groove. 315 is transmitted (acts) only between the outer rail 52 and the outer groove 316, and is not transmitted (acts) between the outer rail 52 and the outer groove 316. DOO without deformation, etc. Such less likely to occur.

  The game board 30 is made of resin. In the case of a game board made of resin, the rail and the game board are particularly slippery and slippery. Therefore, like the pachinko machine 10, the inner groove 315 and the outer groove 316 are fitted to the inner rail 51 and the outer rail 52. A structure in which the displacement in the board direction is suppressed by restricting the relative movement is useful.

(Modification)
The pachinko machine 10 can be variously modified as listed below, for example.

(1) In the above-described embodiment, the front surface of the game board member 301 is configured to protrude forward from the extended ends of the front peripheral wall portions 304T, 304B, 304L, and 304R of the backing member 302. Or in combination with this, at least a part of a mounting surface (that is, the back side surface of the right front wall 12R and the left front wall 12L of the inner frame 12 in the case of the above embodiment) facing the game board member in the gaming machine body. It is good also as a structure which protrudes toward a game board member. FIG. 32 is a schematic cross-sectional view showing an example of the latter configuration. In the example shown in the figure, the front surface of the game board member 471 (the lower extending portion 471E in the figure) and the front surface of the backing member 472 (that is, the extending end of the front peripheral wall portion 474B) are flush with each other. A game board 47 is configured. On the other hand, the right front wall 48R and the left front wall 48L of the inner frame 48 on the gaming machine main body side are formed so as to protrude slightly forward as compared with the case of the above embodiment, and the right front wall 48R of the inner frame 48 is formed. The rear side surface of the left front wall 48L is formed so as to be located slightly in front of the front surface of the front panel (not shown) of the inner frame 48, that is, the position of the mounting surface of the firing rail 38. The left end edge portion of the right front wall 48R and the right end edge portion of the left front wall 48L, which are portions facing the game board member 471 in the inner frame 48, extend slightly rearward, respectively, so that the right contact rib 481R and the left A contact rib 481L is formed.

  When attaching the gaming board 47 to the inner frame 48 on the side of the gaming machine main body, the front surface of the gaming plate member 471 (both edge portions of the lower extending portion 471E in the figure) and the inner frame 48 The front and rear positions of the game board 47 with respect to the gaming machine main body are determined by contacting the extended end faces of the right abutment rib 481R and the left abutment rib 481L that are mounting surfaces facing the game board member 471. At this time, the right side from the right abutment rib 481R on the back side of the right front wall 48R, the left side from the left abutment rib 481L on the back side of the left front wall 48L, and the front surface (that is, the front peripheral wall part) of the backing member 472. Gap 49R and 49L are respectively formed between the extended end of 474B. Also, the contact position T14 between the front surface of the game board member 471 (in the drawing, both side edge portions of the lower extension portion 471E) and the extension end surfaces of the right contact rib 481R and the left contact rib 481L of the inner frame 48, Although T15 is indicated by a cross mark for convenience in the drawing, it is needless to say that the contact here is surface contact between the surfaces. In addition, for example, either one of the extended end of the contact rib and the front surface of the game board member is formed into a line shape (ridge line shape), one or a plurality of dot shapes (cone shape, hemispherical shape, etc.), etc. The contact may be a line contact between a line and a surface, a point contact between a point and a surface, or the like. Further, 48B in the figure is a support surface for supporting the game board 47 in the inner frame 48.

  In this modified mode, the right contact rib 481R and the left contact rib 481L of the inner frame 48 are configured to contact the front surface of the lower extension portion 471E of the game board member 471. A part of the game board member 471 may be in contact with a portion other than the lower extension portion 471E.

(2) In the above embodiment, the lower extending portion 301E, which is a part of the lower end portion of the game board member 301, is configured to extend downward from the lower end of the backing member 302. Or in combination with this, at least a part of a portion of the gaming machine body that faces the lower surface of the game board member (that is, the support surface 12B of the inner frame 12 in the case of the above embodiment) is directed upward toward the game board member. It is good also as a structure which protrudes. FIG. 33 is a schematic partial front view showing an example of the latter configuration. In the example shown in the drawing, the game board 57 is configured such that the lower surface of the game board member 571 (the lower extension portion 571E in the figure) and the lower surface of the backing member 572 are flush with each other. On the other hand, in the inner frame 58 on the gaming machine main body side, the center portion of the surface facing the lower surface of the game board member 571 protrudes upward toward the lower end surface of the lower extension portion 571E, and a contact step portion 581E. Is formed.

  When the gaming board 57 is attached to the inner frame 58 on the gaming machine main body side, the lower surface of the lower extension portion 571E of the gaming plate member 571 is the upper end surface of the contact step portion 581E of the inner frame 58. The upper and lower positions of the gaming board 57 with respect to the gaming machine main body are determined by abutting on and supported on the gaming machine body. At this time, gaps 59R and 59L are formed between the upper end surface of the front panel 58F of the inner frame 58 and the lower end surface of the backing member 572 on the right side and the left side of the contact step 581E of the inner frame 58, respectively. . The contact position T16 between the lower surface of the lower extension portion 571E of the game board member 571 and the upper end surface of the contact step portion 581E of the inner frame 58 is indicated by an x mark for convenience in the drawing. The contact here is surface contact between the surfaces. In addition, for example, either one of the upper end of the contact step portion and the lower end of the game board member is formed in a linear shape (ridge line shape), one or a plurality of dot shapes (conical shape, hemispherical shape, etc.), etc. The contact may be a line contact between a line and a surface, a point contact between a point and a surface, or the like.

(3) In the embodiment, the recessed surface portion 318 </ b> B is formed as a recessed portion in the lower center portion of the back surface of the backing member 302, and the recessed surface portion is formed on the front surface of the ball assembly plate disposed on the back side of the backing member 302. A projection corresponding to 318B is formed, and the ball assembly plate is attached to the back side of the backing member 302 in a state where the projection is fitted into the recessed surface portion 318B. Instead, the backing member 302 is provided. A protrusion may be formed at the center of the lower end of the back surface, and a recessed portion corresponding to the protrusion may be formed on the front surface of the ball assembly plate (not shown).

(4) In the above embodiment, the inner groove 315 of the backing member 302 is formed shallower than the outer groove 316. For example, the inner groove and the outer groove have the same depth, and the inner rail protrudes from the game board. The width may be larger than the protruding width of the outer rail, and when this is done, when the upper game board is stacked on the lower game board, the inner back surface (bottom face) of the outer groove of the upper game board and the lower game board The inner back surface (bottom surface) of the inner groove of the upper game board and the inner rail of the lower game board can preferentially contact with each other in a state where the outer rail does not contact.

(5) In the above embodiment, the inner groove 315 and the outer groove 316 are formed in the backing member 302 as rail fitting portions that can be fitted to at least a part of the rail unit 50. 34, for example, as schematically shown in FIG. 34, it has a substantially partial front surface shape corresponding to the outer periphery of the rail unit 65 of another game board, and is recessed from the back surface of the game board 66, and the rail unit inside. It is good also as the hole 67 into which the whole 65 can be inserted. Alternatively, for example, it may be a protrusion, a rib, or the like that can come into contact with at least a part of a rail of another game board. FIG. 35 is a schematic view showing an example in which ribs are formed as rail fitting portions. In the game board 68 in this example, fitting ribs 71 are provided at a plurality of positions at intervals along the inner periphery of the rail unit 69. When the fitting rib 71 is formed and abuts on the inner peripheral surface of the rail unit 69, the relative movement in the board surface direction between the stacked game boards is restricted. In addition to the grooves formed so as to be recessed inward from the back surface of the game board, such as the inner groove 315 and the outer groove 316 in the above embodiment, the grooves may be formed, for example, from the back surface of the game board. Two protrusions may protrude in the direction, and a rail may be inserted between the protrusions (not shown). However, if the structure protrudes from the back of the game board, such as the ribs and ridges, it functions as a rail fitting portion even if it is formed locally instead of being formed corresponding to the entire rail, for example. However, there is an advantage that it is easier to lay out on the back of the game board, but there is a problem that it is easy to get in the way when storing, storing and handling the game board, and it is easy to break. From the viewpoint, grooves, holes and the like formed so as to be recessed inward from the back surface of the game board are preferable.

(6) In the above-described embodiment, the game board 30 is made of resin, but the material of the game board is not limited to resin, for example, a veneer board generally used conventionally. Wood or the like can also be used. However, as described above, in the case of a game board made of resin, the rail and the game board are particularly slippery and slippery. Therefore, like the pachinko machine 10, the inner groove 315, the outer groove 316, the inner rail 51, and the outer rail 52 are used. The structure which restrained the shift | offset | difference of a board surface direction by restricting relative movement by fitting is useful. Furthermore, in the case of a game board made of a light-transmitting resin, there is a problem that scratches and cracks are particularly noticeable due to light reflection and the like. A structure in which at least a part is covered and protected by the backing member 302 is useful.

When the rail fitting portion of the game board and at least a part of the rail of the other game board are fitted, relative movement in the board direction between the game board and the other game board is restricted. It is characterized by that.

  In the present invention, the “rail fitting portion” can contact, for example, a groove, hole, or at least a part of a rail of another game board that can be fitted to at least a part of a rail of another game board. Any protrusions, ribs, etc. are implied. Further, in addition to the groove formed so as to be recessed inward from the back surface of the game board, for example, two grooves are formed to protrude outward from the back surface of the game board. The thing etc. which were done may be sufficient.

  According to the configuration of the means B1, when a plurality of gaming boards are stacked in the manufacturing process of the gaming machine, the rail fitting portion of the gaming board and at least a part of the rail of another gaming board are fitted. By restricting relative movement of the game board and another game board in the board surface direction, it is possible to prevent these game boards from being displaced along the board surface direction, so that a plurality of game boards can be stabilized. It can be stacked. At this time, in the case of a game board made of resin, for example, the rail and the game board are easily slipped and displaced, but the relative movement is restricted by fitting the rail fitting part and the rail as in means B1. As a material of the game board, any material can be used without considering the degree of slipperiness with respect to the rails while ensuring stability when stacking multiple game boards by suppressing the deviation in the board surface direction. Can also be used.

Further, the gaming machine according to the present invention is a gaming machine of means B1, as means B2.
The rail includes an outer rail and an inner rail, and the rail fitting portion includes an outer groove and an inner groove corresponding to the outer rail and the inner rail, respectively. Are stacked on the other game board, the inner depth of the inner groove of the upper game board is not in contact with the inner depth of the outer groove of the upper game board and the outer rail of the lower game board. The surface and the inner rail in the lower game board are preferentially abutted with each other.

  According to the configuration of the means B2, the upper game board is supported by being supported on the inner rail of the lower game board by the inner inner surface of the inner groove, while the inner inner surface of the outer groove is the lower game. The body is held in a state of being spaced (floating) from the outer rail of the board, so that only the inner rail of the lower game board receives the load of the upper game board. As a result, the load of the upper game board is applied only to the inner rail, and the influence on the trajectory of the shot ball is direct and significantly large, so that no load is applied to the outer rail and deformation or the like is less likely to occur.

In addition, the gaming machine according to the present invention is a gaming machine of means B1 or means B2 as means B3.
The rail includes an outer rail and an inner rail, and the rail fitting portion includes an outer groove and an inner groove corresponding to the outer rail and the inner rail, respectively. When the upper game board and the lower game board try to shift relative to each other in the board surface direction when stacked on the other game board, one side surface and the lower side of the outer groove in the upper game board In a state where the outer rail in the game board is not in contact, one side surface of the inner groove in the upper game board and the inner rail in the lower game board are preferentially in contact with each other.

  According to the configuration of the means B3, for example, when the upper game board is stacked on the lower game board or after the operation, the upper game board and the lower game board are moved along the board surface direction. When some external force is applied that causes the displacement, the external force is transmitted (acts) only between the inner rail and the inner groove, and is not transmitted (acts) between the outer rail and the outer groove. The outer rail, which has a direct and extremely large influence on the trajectory of the launch ball, is not affected by the external force in the direction of the board surface, so that deformation or the like hardly occurs.

In addition, the gaming machine according to the present invention is a gaming machine of any one of the means B1 to B3 as the means B4.
The game board is made of resin.

  According to the configuration of the means B4, in the case of a game board made of resin, the rail and the game board are particularly slippery and slippery. Therefore, the rail fitting part and the rail are fitted to each other as in the present invention. A structure that suppresses displacement in the direction of the board surface by restricting such movement is useful.

  The present invention can be suitably implemented in a gaming machine such as a pachinko machine.
